[Acute abdomen in leukemias in childhood].

During the last years the treatment of acute leukemia became more successful thanks to aggressive chemotherapeutic regimen. There are nowadays about 70% long term survivors in the literature. On the other hand, complications and infection rate following such an aggressive treatment increased. We found in our patients an accumulation of acute abdominal complaints, mostly due to an acute appendicitis. Eight patients had to undergo appendectomy. We tried to answer the question whether there is a correlation between complications and the intensity of chemotherapy. The indication for operation was always proven to be correct, and no patient was lost in the postoperative course.
